Specification of Letters Patent.

Patented my 18,1915.

Application filed December 23, 1913. Serial No. 808,319.

To all whom it may concern:

Be it known that 1, WILLIAM W. COOPER, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful ImprovementsnRailroad-Ties; and I do hereby declare the following is to be a full, clear, and exact. description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in railway ties, and has for its principal object the provision of atie which will be substantially indestructible.

Another object of my invention is the provision of a novel'combination and arrangement of parts which will prevent the rails which are secured to the ties, from spreading and thus causing accidents.

A further object of my invention is toprovide a durable tie which will be composed of a piece of sheet metal bent in the form of a rectangular casing and filled with concrete, thus forming a tie which will be capable of resisting the elements.

A still further object of my invention is the provision of a novel means for absorbing the shock due to the passage of heavy traflic over the road bed.

A still further object of my invention is the provision of a novel combination and a1: rangement of parts by which the rail is firmly clamped in place on the tie without the necessity of using spikes or bolts.

WVith the above and other objects in view, I will now proceed to describe my invention, which consists of a novel combination and arrangement of parts to be more fully hereinafter described.

Figure 1 is a perspective View of a fragment of the tie showing the same as it would appear with a portion of the rail in place. Fig. 2 is a longitudinal sectional view through the tie showing the supporting block for the rail and the rail lockingwedge in section, and Fig. 3 is a longitudinal sectional view taken on line 33 of Fig. 2.

Referring more particularly to the drawings by numerals, 1 indicates the railroad rail of the usual construction comprising a head 2, web 3, and the flanges 4 and 5 respectively. This rail above described, is

preferably placed so that the flange rests upon the shock-absorbingblock, aswill more.

' member 16 the face of which engages the fully hereinafter described; 1

The tie, which is indicated generally by the numeral 6 is preferably formed of a suitable sheet metal casing 7. This sheet metal casing is preferably rectangular in cross section and is adapted to be filled with concrete or a like substance which will make the tie substantially integral. This plastic material is indicated generally by the numeral 8 which may be composed of a suitable aggregate of any of the standard formulas. Near each end of the tie and suitably secured in a recess, I preferably provide the blocks 9 which are of wood, asphalt or any other suitable resilient material which will take up the shock caused by the traffic over the road. The upper surfaces 10 of the blocks are preferably slightly below the upper surface-of the tie, as clearly illustrated in Fig. 2, to form a rail seat in which the flange of the rail is adapted to rest when the degaging extensions 14, I preferably provide, the angular extension 15 which is adapted to engage the wedge block 16 having the wedge face 17 formed thereon, which is adapted to be driven through a pair of rectangular apertures indicated by numerals 18 and 19 and thereby clamp the rail firmly against the block 9 when the device is in use. Should it be so desired, it is to be understoodthat the block 20 may be placed beneath the block 9 to afford further support for said block.

It will be clearly seen from the foregoing that when it is desired to make use of my improved tie, the same is placed on the road in the usual manner with the rail lying upon the block 9. The rail is secured in placeby means of the. clamping member 12 through the action of the web engaging extensions 14:

which is tightly forced against the flange of the rail through the action of the wedge angular extension 15 and forces the same over as the wedge is driven in place.

While in the foregoing I have shown and described the preferred embodiment of my invention, I wish it to be understood that I may make such changes in the co'mbina'tion and arrangementof parts as Will fall Within the scope of the claim herewith submitted.

the tieat points directly beneath the end Walls of the recesses, cushioning blocks arranged to seat Within the tie between the ribs, bearing'blocks arranged to rest on the cushioning blocks and fill the space between the'upper faces of the cushioning blocks and the under faces of the top Wall of the tie,

and a plastic filler Within the tie.

In testimony whereof I aflix my signature in presence oftwowitnesses.

YVILLIAM IV. COOPER.
